Lakrits och vin : En sensorisk studie om hur lakrits påverkar utvalda egenskaper i vin

The key elements of sourdough fermentation are the presence of active lactic acid bacteria (LAB) and yeast. Sourdough fermentation originates from the ancient Egypt. One theory concerning its onset states that a portion of bread dough was set aside to be baked at a later date and started to ferment spontaneously.Sourdough may contain a wide variety of microorganisms, mainly dominated by LAB and yeast. There are over 50 species of LAB that has been identified in various sourdoughs and more than 20 species of yeast. Sourdough fermentation has been shown to have various impacts on baked cereal good, most of which are attributed to LAB.This study addresses some effects of LAB from fermented milk products in sourdough and sourdough bread.

Evaluation of a Flow Cytometry Method for Identifying and Quantifying Fetal Red Blood Cells in Maternal Blood

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

Var man slipad förr? En experimentell undersökning av sandpapprets föregångare.

In this essay I have looked more closely at different means of grinding wood prior to the mass production and total dominance of the sandpaper in recent times as there is virtually no information to be found about this. I have also done a few replicas of how early sandpapers might have looked and as a part of creating these replicas I have also tested diffrent types of early glues. The conclusion of it all is that all the alternative grinding materials tested workd virtually as well as modern sandpaper, with some reservations. And the replicas, although rough, worked mostly well despite being constructed with simplicity in mind. This indicates that an artisan could easily construct sandpapers if he so wished..

Produktionsanpassad tvärkraftsarmering för betongplattor

AbstractThe project "Sound and Play" have been implemented in collaboration with the toy company BRIO in Malmo. The purpose of the project was to examine whether and how BRIO in the future could develop toys around sound for Toddlers.The problem formulations that would be answered after completion of the project was "How could BRIO broaden its product range with the help of audio toys?", "How can you combine toys and sounds in an interesting way for children?", "How do you create a toy with sound that is fun for the child, but not annoying for parents?". Currently BRIO only has two toys with sound in this age group.The expression of the toy was going to be a mix of classic and cool and the overall feeling of the toy was going to be explorative and arouse curiosity in the child. This feeling would be communicated through simplicity and joy.

Information som inspiration : en studie av yrkesverksamma konstnärers behov och användning av information

The main purpose of this essay is to investigate professional artists experience of the need and use of information in their creative work. I have collected the material through qualitative interviews with four professional artist working with different materials and techniques. One of the results of the study is that the artists first of all used information as a source of inspiration in their creative work. They gathered their information from various scources, for example; pictures, exhibitions, visual arts, books and novells, depending on what project they are working with. Other important information scources were colleges, especially for the technical information need.

Competition for forest fuels in Sweden : exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework

This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).

Tuftade ljudabsorbenter ? väggpaneler för rumsliga och akustiska egenskaper

It is a well-known fact that textiles and carpets have benign sound-absorbing properties. It is desirable to have quantified values of these properties ? especially for architects and interior designers. They often need to be able to giveaccount for the acoustic properties of their designs at a relatively early stage and sometimes have strict acoustic classifications imposed upon them by their contractor. A product with documented acoustic properties would aid when prescribing interior elements.The purpose of this thesis is to develop a wall-mounted panel in hand-tufted material ? aesthetically pleasing and versatile but also having documented and quantified acoustic properties.

Tilläggsisolering inom byggnadsvård

Främsta anledningen till en tilläggsisolering är att det önskas bättre energihushållning i en byggnad. Detta kan göras med olika material och olika tekniker. Inom byggnadsvårdssammanhang förs det en diskussion om de fuktbuffrande materialen är bättre vid tilläggsisolering då de är hygroskopiska än de icke hygroskopiska som är mest frekvent använda i det konventionella byggandet. Denna rapport utvärderar om det finns några dokumenterade fakta som styrker att de hygroskopiska och ekologiska materialen fungerar bättre i byggnadsvårdssammanhang än de icke hygroskopiska. Olika isolermaterial från de två nämnda grupperna jämförs utifrån olika parametrar..

En belysning av Lean Production : teori och praktik ur två synsätt

Syfte: Syftet med studien är att belysa forskning och litteratur kring Lean Production utifrån två vetenskapliga synsätt. Studien syftar även till att undersöka en organisations införande av och arbete med Lean Production, för att kunna ge praktiska bidrag om hur detta arbete kan fortskrida.Metod: Studien har genomförts med en kvalitativ och öppen ansats inom ramen för en fallstudie i samarbete med Sandvik Materials Technology. Empiriskt material har samlats in genom intervjuer och observationer med och av operatörer, produktionsledning och stabspersonal. En omfattande analys av litteratur och forskning kring Lean Production har legat till grund för en teoretisk referensram.Resultat & slutsats: Belysningen av Lean Production visar att systemsynsättet beskriver konceptet som ett säkert recept för framgång, trots sin förenklade syn på organisationers påverkan av omvärldsförändringar. Det socialkonstruktivistiska synsättet visar att Lean Production har en legitimerande funktion i organisationer, men ger liten kunskap om de förändringar som sker i organisationer.

Korridorsliv : En kvalitativ studie om förhållandena i studentkorridorer

This thesis is dealing with how students living in a student corridor experience the circumstances in their corridor. The aim is through interviews with students living in the corridors get a inside look at their situations. I want to examine how changed conditions of life, new meetings and new experiences will influence their personalities. How are the students living in the corridors affected by conflicts and how do they protect themselves from the influence of the rest of the group living there? In addition to that I want to know what they think is important prioritises throughout their student time, like if there are anything important that a student should take time to do beside the studies.
